JDBC Connection Metadata

JDBC Connection Metadata

After you create a JDBC connection, save the connection. You can then publish the JDBC connection and click the
Metadata
 tab to view the generated process objects for the connection.
When you publish a JDBC connection, a list of
Objects
 appear in the
Metadata
 tab. The
Objects
 section displays the entities along with the column metadata for the schema you specified in the connection. You can also preview the data.
The following image shows the
Metadata
 tab for a published JDBC connection:
The image shows two entities named Customer and Invoice along with the column metadata and data.
When you publish a JDBC connection, the
Metadata
 tab is refreshed by default. You can click
Publish - Skip Metadata Refresh
 to skip the metadata refresh and reduce publishing time.

Best practices for metadata refresh

  • When you create a JDBC connection for the first time, click
    Publish
     to download the metadata. Subsequently, you can click
    Publish - Skip Metadata Refresh
     if there are no metadata changes.
  • If you want to change credentials in a JDBC connection but you know that the metadata has not changed, skip the metadata refresh while publishing the connection to apply just the credential changes.
  • If you know that the metadata has changed, you must click
    Publish
     to retrieve the metadata changes.
